Link ECU G5 Plug-In ECU – Toyota 86 / GT86, Subaru BRZ, Scion FR-S (FA20)

Link ECU G5 Plug-In ECU for Toyota 86 / GT86, Subaru BRZ, and Scion FR-S. This is a standalone plug and play replacement for the factory ECU that plugs straight into the original wiring loom with no adapter harness needed. It includes a sample map to give you a head start, and it runs the same powerful microcontroller and firmware as the G5 Voodoo Pro.

Engine and transmission support

Designed for the 2.0 L 4U-GSE / FA20 H4 engine. Supports both manual and automatic transmissions.

Models supported

• Toyota 86 ZN6, 2012-2021
• Toyota GT86 ZN6, 2012-2021
• Subaru BRZ ZC6, 2012-2020
• Scion FR-S ZN6, 2013-2016

LHD vs RHD part numbers

• LHD version: 241-4200
• RHD version: 241-4000

Due to the very tight factory ECU location, the mounting method differs between left-hand drive and right-hand drive cars. Order the correct version for your vehicle.

Key features

• Direct plug-in to the OEM harness with OE-style connectors
• Full OEM CAN bus integration
• Controls both direct and port injection
• Full factory electronic throttle (DBW) control
• Full VVT-i control
• Control for both manual and automatic transmissions
• Billet CNC aluminium enclosure that mounts in the OEM location
• 512 MB onboard data logging, up to 250 channels and 100k samples per second

Note: The GT86 plug-in does not support the factory wide band sensors.

All Link Plug-In ECUs include

• Plug and play direct replacement for the factory ECU
• All motorsport features enabled: anti-lag, boost control, cruise control, gear shift control, nitrous control, launch control, paddle shift control, race timer and power management, rolling anti-lag, and traction control
• Two CAN bus channels with flexible, user configurable CAN I/O and support for most third-party CAN devices
• Advanced modelled fuel equation with flex fuel capability, or optional Traditional fuel equation
• Exceptional adaptive knock control or traditional threshold-based knock control
• Onboard 3-axis accelerometer and trigger oscilloscope
• Live user configurable math channels running in the ECU
• Flexible engine protection limiters
• PCLink software for tuning, display, and powerful log analysis

2017+ model setup notes

2017 and later vehicles differ from earlier cars and will not run with the sample maps supplied in PCLink and the standard plug-in ECU hardware without the changes below:

• Crank sensor: 2017+ engines have a Hall effect crank sensor instead of a reluctor. Set Trigger 1 Type to Optical/Hall and set the Trigger 1 Pull-up to ON.
• DI fuel pressure sensor: 2017+ engines use a 4-pin sensor (earlier cars are 3-pin). Wire an 8.2 kΩ pull-up resistor between C7 (An Volt 4) and 5 V. Change the DI Fuel Pressure Source from An Volt 3 to An Volt 4, and set the calibration to 0 kPa at 4.06 V and 30000 kPa at 0.46 V.

What’s in the box

• G5-GT86 Plug-In ECU
• USB-C connection cable
• Locking USB-C extension cable for easy tuning access
• 2 x M6 screws for mounting in the OEM bracket
• DTM4 CAN connection cable pre-installed in the enclosure
• Link stickers
